TL;DR: Annular dark-field imaging in an aberration-corrected scanning transmission electron microscope optimized for low voltage operation can resolve and identify the chemical type of every atom in monolayer hexagonal boron nitride that contains substitutional defects.

TL;DR: This work has designed and built an entirely new scanning transmission electron microscope (STEM), which includes a flexible illumination system that allows the properties of its probe to be changed on-the-fly, a third-generation aberration corrector which corrects all geometric aberrations up to fifth order, an ultra-responsive yet stable five-axis sample stage, and a flexible configuration of optimized detectors.

TL;DR: An all-magnetic monochromator/spectrometer system for sub-30 meV energy-resolution electron energy-loss spectroscopy in the scanning transmission electron microscope is described, which will allow it to attain spectral energy stability comparable to systems usingmonochromators and spectrometers that are raised to near the high voltage of the instrument.

TL;DR: A novel method to produce solution-phase triangular silver nanoparticles is presented and Mie theory and the Discrete Dipole Approximation method have been used to model and interpret the optical properties of the released Ag nanoparticles.

TL;DR: A parallel imaging pipeline using transmission electron microscopes that scales this technology, implements 24/7 continuous autonomous imaging, and enables the acquisition of petascale datasets is built.
